Synopsis
zlib bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated zlib package that fixes two bugs is now available for Red Hat
Enterprise Linux 5.
Description
Zlib is a general-purpose lossless data compression library that is used by many
different programs.
This update fixes the following bugs:
- When used to combine two Adler-32 checksums, the adler32_combine() function
could occasionally produce an incorrect result. With this update, an upstream
patch has been applied to fix the underlying algorithm, and the
adler32_combine() function no longer returns incorrect checksums. (BZ#622779)
- Previous versions of the zlib package installed shared libraries to the
/usr/lib directory (on 64-bit systems, also in /usr/lib64). Consequent to this,
when the /usr directory was on a separate partition, certain applications may
have been unable to start before this partition was mounted. This update changes
the installation target for these libraries to /lib (and /lib64 on 64-bit
systems) to ensure that these libraries are available before /usr is mounted.
For compatibility reasons, the /usr/lib directory (on 64-bit systems, also
/usr/lib64) now contains symbolic links to these libraries. (BZ#678352)
All users are advised to upgrade to this updated package, which fixes these
bugs.
Solution
Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
